Kiran says that -2 < -5 . do you agree with Kiran?b explain or shoe your reasoning

Answer:

Step-by-step explanation:

To simplify the expression 24 + b/b + 24 x 53.72,

we first need to substitute the given value of b into the expression.

For example, if b is equal to 5, we can replace all instances of b with 5 to get 24 + 5/5 + 24 x 53.72.

Next, we can simplify the division by evaluating 5/5, which equals 1.

Then, we can multiply 24 and 53.72 to get a product of 1288.28.

Finally, we can add the simplified terms to get a final result of 1312.28.

Therefore, the simplified expression, given that b is equal to 5, is 1312.28.

The graph provides visual information about the shape and characteristics of the function, but not enough details to determine the exact coefficients of the quadratic expression.

To find the formula for a quadratic function, we need to know three coefficients: a, b, and c. These coefficients are determined by the specific shape and features of the graph, such as the vertex, intercepts, and symmetry.

Step-by-step explanation:

To calculate the amount of wood needed to create a raised bed, you will need to know the dimensions of the bed.

Assuming the raised bed is rectangular, you will need to know the length and width of the bed, as well as the height of the bed.

Once you have these dimensions, you can calculate the surface area of the raised bed by multiplying the length and width of the bed together. This will give you the area of the bottom of the bed.

To calculate the total surface area of the bed, including the sides, you will need to multiply this area by 2 (since there are two sides) and add this to the area of the bottom.

So the formula for calculating the total surface area of the raised bed is:

Total surface area = (2 x length x height) + (2 x width x height) + (length x width)

Once you have this total surface area, you can then calculate how much wood you need by multiplying it by the thickness of the wood.

For example, if the total surface area of the bed is 100 square feet and you plan to use 2-inch-thick boards, you would need 200 cubic feet of wood.

It's worth noting that this calculation assumes that the raised bed has straight sides and right angles. If the bed has a more complex shape, the calculation will be more difficult.

Answer:

Step-by-step explanation:

The value of sin 90° is 1, so we can simplify the expression as:

16 sin 10° sin 30° sin 50° sin 70° sin 90° = 16 sin 10° sin 30° sin 50° sin 70°

We can use the identity sin (90 - x) = cos x to rewrite sin 70° as cos 20°:

16 sin 10° sin 30° sin 50° sin 70° = 16 sin 10° sin 30° sin 50° cos 20°

We can use the identity sin (180 - x) = sin x to rewrite sin 170° as sin 10°:

16 sin 10° sin 30° sin 50° cos 20° = 8 sin 10° [2 cos 20° sin 30° sin 50°]

We can use the identity sin (2x) = 2 sin x cos x to simplify the expression inside the brackets:

8 sin 10° [2 cos 20° sin 30° sin 50°] = 8 sin 10° [sin 100° - sin 20°]

We can use the identity sin (180 - x) = sin x to rewrite sin 20° as sin 160°:

8 sin 10° [sin 100° - sin 20°] = 8 sin 10° [sin 100° - sin 160°]

We can use the identity sin (x + y) = sin x cos y + cos x sin y to rewrite sin 100° as sin (60° + 40°):

8 sin 10° [sin 100° - sin 160°] = 8 sin 10° [sin 60° cos 40° + cos 60° sin 40° - sin 160°]

We can use the identity sin (180 - x) = sin x to rewrite sin 160° as sin 20°:

8 sin 10° [sin 60° cos 40° + cos 60° sin 40° - sin 20°] = 8 sin 10° [sin 60° cos 40° + cos 60° sin 40° - sin 20°]

Now, we can use the values of sin 60°, cos 40°, and sin 20°, which are:

sin 60° = √3/2

cos 40° = √[(1+cos 80°)/2] = √[(1+sin 10°)/4]

sin 20° = sin (60° - 40°) = sin 60° cos 40° - cos 60° sin 40° = (√3/2)(√[(1+sin 10°)/4]) - (1/2)sin 10°

Substituting these values into the expression, we get:

8 sin 10° [sin 60° cos 40° + cos 60° sin 40° - sin 20°]

= 8 sin 10° [√3/2 × √[(1+sin 10°)/4] + 1/2 × sin 10° - (√3/2) × √[(1+sin 10°)/4]]

= 2 √3 sin 10° √[(1+sin 10°)/2]

The function for this problem is defined as follows:

f(x) = -1/x - 4.

As x goes to infinity, the term 1/x goes to zero, hence the end behavior of the function is defined as follows:

Answer: We can start by noticing that the total number of small cubes used is 64, which is the same as the total number of unit squares on the surface of the large cube. To maximize the white surface area, we want to arrange the cubes in a way that maximizes the number of white faces on the surface.

Each small cube has 6 faces, so there are a total of 6 x 64 = 384 faces. Half of these faces are white and half are black, since we have an equal number of white and black cubes. Therefore, there are 192 white faces and 192 black faces.

Now, let's consider how the small cubes can be arranged to maximize the white surface area. If we arrange all the white cubes together in a 4 x 4 x 4 block, then all the faces of this block that are adjacent to a black cube will be black, and all the faces that are adjacent to another white cube will not contribute to the surface area. This leaves only 16 white faces that contribute to the surface area.

On the other hand, if we alternate white and black cubes in each layer of the cube, then all the faces that are adjacent to a black cube will be white, and all the faces that are adjacent to another white cube will be black. This maximizes the white surface area. Specifically, there are 6 layers of the cube, and each layer has 16 white faces (4 along the top and bottom and 4 along each side). Therefore, there are a total of 6 x 16 = 96 white faces that contribute to the surface area.

So the fraction of the surface that is white is:

96 white faces / 384 total faces = 1/4

Therefore, one quarter of the surface area of the cube is white.

a. Graphing the system of linear inequality, the solutions are (0.7, -3.35)

b. To prove that the inequality remains true at any given point, we can use a test point. We will choose the point (0,0) as our test point.

For the first inequality, plugging in (0,0) gives:

4(0) + 8(0) ≤ -24

0 ≤ -24

This is clearly false, so (0,0) is not a solution to the first inequality. This means that any point below the line 4x + 8y = -24 will not satisfy the inequality.

For the second inequality, plugging in (0,0) gives:

12(0) - 4(0) < 5

0 < 5

This is true, so (0,0) is a solution to the second inequality. This means that any point to the left of the line 12x - 4y = 5 will satisfy the inequality.

Therefore, the system of inequalities will only be satisfied by points that are both below the line 4x + 8y = -24 and to the left of the line 12x - 4y = 5.

Answer:

Amount of benzoic acid in the solvent phase = 0.303 kg/L * 100 L/min * 20 min = 606 g.

Step-by-step explanation:

To determine the amount of benzoic acid that has passed into the solvent phase after 20 minutes, we need to use the given simplifications to set up a mass balance equation.

Let's express the stream-flow rates on a solute-free basis, which means that we consider only the flow rate of the solvent (water) and the flow rate of the toluene (ignoring the mass of benzoic acid in each stream). Let Fw be the flow rate of water and Ft be the flow rate of toluene.

Since the toluene and water are immiscible, we can assume that the volume of the two phases leaving the tank is the same as the volume of the mixture entering the tank (which is 100 L/min). Let V be this volume, which is also equal to the volume of the tank (120 L).

Let x be the concentration of benzoic acid leaving the stage in the organic phase (i.e., the solvent phase), and y be the mass concentration of benzoic acid in the aqueous phase.

From the given simplification, we have:

y = 5x

Let's use the mass balance equation to relate the flow rate of benzoic acid entering the tank to the flow rate of benzoic acid leaving the tank:

FtCt,in = VxCt,out + (FwCw,in - Fw*Cw,out)*y

where Ct,in and Cw,in are the concentrations of benzoic acid in the toluene and water entering the tank, respectively, and Ct,out and Cw,out are the concentrations of benzoic acid in the toluene and water leaving the tank, respectively.

We can assume that the feed concentration is constant, so Ct,in = 0.12 kg/L. We also know that the flow rate of the toluene and water entering the tank are 100 L/min and 110 L/min, respectively.

The concentration of benzoic acid in the water leaving the tank is given by:

Cw,out = y/5 = x/5

Since the flow rate of each phase is steady, we can assume that the concentration of benzoic acid in the toluene leaving the tank is the same as the concentration of benzoic acid in the toluene entering the tank, which is also 0.12 kg/L.

Substituting these values into the mass balance equation, we get:

1000.12 = 120x*0.12 + (110 - 120)*y

Simplifying, we get:

12 = 14.6x + 10y

Substituting y = 5x, we get:

12 = 39.6x

x = 0.303 kg/L

Therefore, the concentration of benzoic acid leaving the tank in the organic phase is 0.303 kg/L.

To find the amount of benzoic acid that has passed into the solvent phase after 20 minutes, we need to multiply the concentration by the flow rate of the toluene:

Amount of benzoic acid in the solvent phase = 0.303 kg/L * 100 L/min * 20 min = 606 g.

We can use the mass balance equation to solve this problem. Let x be the concentration of benzoic acid leaving the stage in the organic phase (in kg/L) and y be the concentration of benzoic acid in the aqueous phase (in kg/L). Then we have:

Mass of benzoic acid entering the stage per minute = Mass of benzoic acid leaving the stage per minute

The mass of benzoic acid entering the stage per minute is:

100 L/min x 0.12 kg/L = 12 kg/min

The mass of benzoic acid leaving the stage per minute can be expressed in terms of x and y as:

100 L/min x (0.12 kg/L - x) + 110 L/min x y = (100 + 110) L/min x m x x

Simplifying and using the given linear relationship between y and x, we get:

12 - 100x + 110(5x) = 210x

Solving for x, we get:

x = 0.034 kg/L

Therefore, the concentration of benzoic acid in the organic phase after 20 minutes is 0.034 kg/L.

The simple rate of return for the investment (rounded to the nearest tenth of a percent) is: 0.1572 or 15.7%.

Simple rate of return is a financial metric used to measure the profitability of an investment, calculated as the ratio of net income to the initial investment.

To calculate the simple rate of return for the investment, we need to first calculate the average annual net cash inflow.

Annual net cash inflow = Annual cash inflows - Annual depreciation expense

The annual depreciation expense can be calculated as:

Depreciation expense = (Initial cost - Salvage value) / Life of investment

Depreciation expense = ($34,000 - $0) / 15 years = $2,266.67 per year

Therefore, the average annual net cash inflow is:

Annual net cash inflow = $7,600 - $2,266.67 = $5,333.33

The simple rate of return can now be calculated as:

Simple rate of return = Average annual net cash inflow / Initial investment

Simple rate of return = $5,333.33 / $34,000 = 0.1572 or 15.7% (rounded to the nearest tenth of a percent)
